My invention has relation to printing-telegraphs; and it consists in the improved construction, arrangement, and combination of and pointed out in the claims.

Referring to the several parts by letter, A A represent the, key-boards, of wood or other non-conducting material, of which: there is one at each end of the line-wire C: B B indicate the recording-inastruments, of which there is also one at each end of the line C; and

` C indicates the main-line wire or wires, the

apparatus using ve wires, one for each of the recording-levers, which separately or in combination print the different characters of the alphabet, as hereinafter described.l p

D D indicate the batteries i-n the local circuits at each end of the line, and lE E indicate the ground-places with which one wire of each battery communicates in the usual manner.

button, H', for the fingers.

' The keys of each keyboard consist of a series of Morse keys arranged similar to the keys of the Bartholomew stenograph, there being on each key-board a central key, F, and four keys on each side of the said central key,

each of the keys having upon its outer end a `A is centrally pivoted upon a short metallic fulcrum-post, M, the rear ends of the keys resting normally upon metallic posts I, while beneath their freeends, and in a position to be touched by the same when the keys'are depressed by the fingers of the operator, are metallic buttons J. rlhe pairs of posts I of each key-board corresponding to each other are connected together by means of wires K, passing out at one side to the local recordinginstrument at that end of the' line, and the posts J, corresponding to each other, are similarly connected to each other by wires L, passing out at one side of the key-board to the lo- Each of these keys 6o cal battery D, while the fulcrum-posts M of the keys corresponding to each other are connected by wires N, which pass out at one side of the key-board and pass into the line-wires, each key at one side ot' the middle key having"a key corresponding to it uponv the other side of the said central key, with which it is coupled, as above described. rlvhe object of this arrangement is to enable the operator to use the 'ingersof both hands in telegraphingffaslto touch any key to the side of the central key produces. the same result as touching its coupled key on the other side' of the central key, and by thus enabling the operator to use both hands a great degree of rapidity is' attained, the hands working alternately, as it were, much more rapidly than one hand alone could work.

The recordingins'truments, one of which, as previously stated, is located at each end of the line, are each provided with five electro- 'l magnets,0, and one end,O, of the wire of each. of these magnets is connected with a wire, K, from one pair of posts I at'the inner, ends of the keys of the key-board, while the other end, P, of the wire of each magnet passes to the ground-wire Q of the battery, each electro-magnet corresponding to and being operated by one pair 'of coupled keys upon the key-board, with the exception of one electromagnet, which is connected in asimilar Inan- IOC ner to the central key, F. The armatures of each of these electro-magnets are secured upon the outer ends of levers or type-bars S, which levers are centrally pivoted and have their inner ends arranged in a straight row, and provided each with a head, T, having a straight dash upon its face, the dashes upon the faces of the five heads forming a straight line transverse to the length of the paper ribbon which travels above them.

YZ indicate twoparallel frame-pieces which are secured upon the base of each recordinginstru1nent,Y representing the front framepiece and Z the rear frame-piece,and between the upper ends of these frame-pieces is journaled a roller or cylinder, X, beneath which passes a paper ribbon, U, which is wound upon a roller or disk, V, journaled between two uprights, XV W, rigidly secured at one side of the frame-pieces Y Z. The cylinder X is provided at its forward end with a ratchet-wheel, A', and a pawl, R', pivoted upon the inner side of the front frame-piece,Y, engages with the said ratchet-wheel and thereby prevents the cylinder X from turning in the wrong direction.

E' represents a vertical bar which slides in a Vertical opening in the front frame-piece,Y, the said bar being provided with a springcatch,C',which engages with the ratchet-wheel A', and the bar E' is also formed at its lower end with a transverse bar, D', which is transverse to the inner ends of all the armature-levers S,extending above them forward of their operative straight ends, so as not to prevent the said ends from coming in contact with the paper ribbon, as hereinafter described. The upper end of the vertical sliding bar E is secured to the lower end of a spring.Y F,which is coiled in a recess,G, on the front frame-piece, Y, and bears with its upper end against a -plate, H', at the lower end of a set-screw, l',

working in the upper portion of the front frame-piece, the said screw serving to adjust the tension of the coiled spring F'.

To the rear end of the shaft of the cylinder X, beneathwhich the paper ribbon passes,and which may be denominated the "paper-carrying cylinder,7 is securedacog-wheel, J', which meshes with a cog-wheel, K', which is pivoted at the outer end of an arm, which is in turn pivoted at its inner end upon the rear end of the shaft of the paper-carrying cylinder, so that the said cog-wheel may be swung upon the arm from one side of the papercarrying cylinder to the other and still continue to mesh with the cog-wheel upon the rear end of the cylinder-shaft.

OL indicates the inking-ribbon, which is wound at each end around aroller, N', the said ribbon-carrying rollers being journaled between the front and rear side pieces of the frame in such positions as to carry the ink ing-ribbon immediately beneath the papercarrying cylinder X. The rear end of one of these rollers is provided with a pinion, M',

with which the cog-wheel K'lmeshes when the pivoted arm L' is swung to that side, while when the arm L' is swung to the opposite side the wheel K' meshes with the small pinion P', 7o interposed between it and the pinion M' on the other roller, by which arrangement the second roller is caused to revolve in a direction opposite to that in which the first roller revolves, so as to carry the ribbon back when it 7 5 has been all wound upon the said rst roller.

An arm, Q', is pivoted at one end between the uprights V W, and has a short arm projecting to the outer side ofthe uprights, through a perforation in which arm passesa set-screw, 8o R', having attached to its lower end a spring,

S', the other or lower end of the said spring being secured to the base of the instrument, and the inner end of the arrn Q' is'provided with a guide-bail, T', through which the pa- 85 per ribbon passes, while the innermost end of the arm has a roller, U', `journaled in it, which bears against the under side of the paper ribbon, pressing it against the paper-carrying cylinder, and by means of the set-screw R' the 9o spring-tension with which the roller U' presses against the paper may be readily adjusted.

A second roller, U2, is `journaled in the side pieces of the main frame, so as to press against the paper ribbon on the opposite side of the cylinder X, as shown, thereby holding the paper ribbon up firmly against the said cylinder.

The operation of my improved apparatusis as follows: The rear ends of the keys on each ico key-board rest normally in contact with the rear posts, I, thereby communicating,through their wire-connections K, with the electromagnets of the recording-instruments, the armature-levers S resting normally with their :o5 rear ends lowered, and their free ends, which carry the armatures, elevated above and out of Contact with their electro magnets. 'When the operator at one end of the line-say, for example, at the station marked A5 on the 1 Io diagram, Fig. l of the drawings-wishes to send a message to the station at the other end of the line, he depresses one or more keys, according to the number and position of the dashes required to indicate the desired letter, i r 5 (I prefer to use the alphabet used with Bartholomews stenograph,) and when the forward end of the key or keys is depressed to touch the buttons J beneath them the current from the battery D will pass through the wire 12o L, button J, the depressed key, the fulorum M of the same, thewire N, through the mainline wire C, through the fulerum-post of the corresponding key, the key, andthe rear post,

I, of the key-board at the other cnd,A, of the 12 5 line, and through the wire K of the said rear post to the corresponding electro-magnet, which is thereby electrified or actuated, and

by attracting or drawing down the armature of its. type-bar S will elevate the rear end 13o of the said type-lever, which will strike against theinking-ribloon and make an imindicating the required letter, will be printed at the other end of the line, and the message will stand recorded upon the paper ribbon, so that it will not be absolutely necessary for the operator to be present at the moment of receipt. When the rear end of the type-lever strikes upward to print the dash, it elevates the sp ri ng-cushioned transverse bar D', against which it strikes, and on thedescent of the type-lever the bar E will be forced down by its spr-ing, and in its descent the spring-pawl C', attached to it, will engage the ratchet-wheel A upon the paper-ribben cylinder, thereby moving the same and the paper ribbon with it one' space ahead. As the paper-carrying cylinder revolves it will revolve one of the rollers carrying the inking-ribbon, causing the said ribbon to wind upon the said roller, and after the said ribbon has been completely wound upon one roller the swinging arm`L may be swung over tothe other side, causing the cog-wheel K to engage with'the pinion upon the end ofthe other roller, or the small intervening pinion,P', as the case may be, thereby causing theinking-ribbon to be wound in the opposite direction.

It will be seen from the foregoing that when the keys at one end of the lineare depressed the current from the battery at that end will pass through the depressed keys, their fulcrums, andthe main-line wires to the fulcrums of the keys at the distant station through the said keys, which are in contact with their rear posts, I, to the electro-'mag` nets, thereby attracting the armatures of the corresponding type-levers, the rear ends of which are thus elevated to print the desired dash or dashes, the upward stroke of the lever or levers raising the transverse bar D', which in falling moves `the recording-paper and inking-ribbn forward one' space, as above described.

Eachrecorder is represented as having an individual line-wire, but my apparatus may be used in connection' with anywell-known multiplex system of transmission.

Having thus described my invention,l"claim and desire to secure by Letters Patent of the United States- 1.
